i LOOM SHUTTLE-RELOADER.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed August 1, 1913. Serial No. 782,461.

To all whom it may concern Be it known that'I, SIMEoN S. JAoKsoN, a subject of Great Britain, residing at Readville, Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Loom Shuttle-Reloaders, of which the following is a specification, reference being had therein to the accompanying drawings. 7

The invention provides a manually-con trolled loom-shuttle reloader by means of which a weaver or a helper can introduce readily, at convenience, a fresh bobbin or other weft-carrier into a spent shuttle that has been removed from its place on the lay of a loom. v

One general object of the invention is to render it practicable to use in ordinary looms, and in shuttle-changing automatic \vefhreplenishing looms, shuttles constructed without the usual hinged spindle and having instead thereof one or more holding clips or retainers engaging with a bobbin or other weft-carrier to hold it in place in a shuttle. In this connection one of my special aims is to facilitate the employment in shuttle-changing weft-replenishing looms and ordinary looms of shuttles of the said class of the type at present used only in bobbin-changing replenishing looms. These are constructed to permit a bobbin or other weft-carrier to be inserted into the same by being pushed bodily in at one side of the shuttle, and to be ejected by being pushed bodily out through the other side thereof. Such shuttles have an opening through the same from top to bottom, the insertion being effected at the top and the ejection at the bottom. They usually are furnished with one or more clips or retainers therein to hold the bobbin or other weft-carrier in place within the shuttle. The usual clip or retainer performs the said function by engaging with the head or base of the bobbin or other weft-carrier, the said head or base being pushed bodily into the grasp of the clip or retainer as the bobbin or weft-carrier is inserted into the shuttle, and beingpushed bodily out of such grasp as the bobbin or weft-carrier is ejected. The clip or retainer is constructed to take a powerful and firm holdupon the head or base of the weftcarrier, in order'to prevent the Weft-carrier from being dislodged'during the working of theloom, and inorder to prevent the free end of' the weft-carrier and its yarn-load from swinging either upward or downward. Owing to the inconvenience and diiiiculty of insertingor changing bobbins or other weftcarriers by hand in the case of shuttles of this class, such shuttles are not employed at the present time in. ordinary looms, and have been employed only to a limited extent in shuttle-changing weft-replenishing looms. Instead, shuttles having hinged spindles are employed, because of the greater facility lninserting and changing bobbins, etc., by hand therein. At the present time I know of no devices for use by a weaver or helper for manually effecting the insertion or change ofbobbins or other weft-carriers in the case of a spent shuttle of the class in question that has been removed from a loom.

Another general object of the invention is to facilitate the reloading of shuttles so as other duties, and also so as to obtain the very important result of considerably increasing the number of plain looms, or shuttle-changing weft-replenishing looms, that can be tended by a weaver, and also, in the case of shuttle-changing weft-replenishing looms, the number of looms that a bobbin-boy can take care of by keeping the shuttles loaded with weft and threaded and in place in the magazines of the looms.

The invention consists in a manually-controlled reloader for loom-shuttles having a through-passage for insertion and discharge of filling-carriers and a clip which holds a filling-carrier I within the shuttle by grasping the head of the filling-carrier, for enabling an operative to effect the reloading of a shuttle which has been removed from a loom in which it is employed, the said reloader comprising a shuttle-rest for a shuttle free from the loom, a weft-carrier inserter distinct and separate from the regular weft-replenishing instrumentalities of a loom, and means for operating the parts at the willof the operative to insert a fresh weft-carrier into theclip or other grasping means of a shuttle applied manually to the said shuttle-rest.

a The invention, in several forms of em-t bodiment, is illustrated by the accompanying drawings, in which latter I Figure 1 shows in front elevation certain portions of the magazine-ends of two adjacent shuttle-changing weft-replenishing to give a weaver more time to attend to I looms,

and a-shuttle reloader of one form between them. Fig.2 is a plan view of certain of the parts shown'in Fig. 1. Fig. 3 is a'partly sectional side elevation of the upper portion of theshuttle reloader of Figs. 1 and 2. Fig. 4 is a front elevation of another form of shuttle reloader. Fig. 5 is a plan view thereof. Fig. 6 is a side elevation thereof partly in vertical section on line 6, 6, of Fig. 4. 1

Having reference loomswhich are shown partly to the drawings, the two tomatic shuttle-changing weft-replenishing loom shown and described in U. S-Letters to bobbin-changing weft-replenishing looms,

namely having a weft-chamber which is open at both the top and the bottom of the shuttle'so that an opening or through passage extends entirely through the shuttle from its top surface to its bottom surface. Each thereof is provided with a U-shaped spring clip orfretainer 3*, Fig. 2, designed for engagement with the head or base of a weftcarrier w, and permitting such weft-carrier to be inserted into place within the shuttle by being forced down from above into the weft-chamber, so that its head'or base shall enter between the engaging members of the said clip or retainer, and also permitting the said weft-carrier to be expelled from the shuttle by being forced downward from the weft-chamber through the bottom of the shuttle, thereby withdrawing its head or base from between the said engaging members. The pegs or pins 4, 4, on the said hoppers or magazines'have wrapped around the same the leading weft-ends which are drawn out through the eyes of the said shuttles, in usual manner. In the working of the said looms, weft-replenishment is efiected by the automatic discharge from the lay of a loom of the shuttle previously at work thereon, and the automatic transfer of a fresh or reserve shuttle fromthe hopper or magazine to the lay to take the place of'the shuttle which has been thus discharged.

At 5, 5, are the catcher-boxes in which the spent shuttles are rece ved when they are discharged from the respective looms.

Referring now to the shuttlereloader,

and first to in this instance ismounted upon 'a post or standard 7 stationed between the magazineends offthe two neighboring looms. The adfor both looms,

in Fig. 1 may be, for instance, of the character of the au- 7 bolts serving to attach bed or shelf.

7 about a pivotal support Figs.'1,2 and 3, the shuttle-rest thereof consists of a bed or shelf 6, which Figs. '2 and loader is that a weaver or helper standing at the shuttle-reloader is within reaching d1s shuttle-'reloader, and place it in the magazine of the loom in which it is employed. In other words, the shuttle-reloader serves enabling the expelled shuttles of both looms to be reloaded and replaced in the respectlve magazines practically without change of position on the part of the operative who performs the work of reloading. For the proper positioning of a shuttle which is to have a weft-carrler placed therein, the shuttle-rest is furnished with end-gages 8, 8. present instance are shaped to receive and fit the opposite ends and tips of a shuttle contacting with the top surface of the bed or shelf 6, andposition ofthe shuttle lengthwise with relation to the pusher 9 and the discharge-openmg 6*, Fig. 3, through the shuttle-rest. The

said discharge-opening is indicated in dotted lines in Fig. 1. The end-gages are secured in place by means of extensions thereof These end-gages in the I hey serve to determine the which are engaged by bolts 10, 10, the said. i

the end-gages to the To provide for adjustment of the end gages to suit the length of the shuttles, and to cause the shuttles to assume the proper position relative to pusher 9 and dis charge-opening 6 the said extensions are slotted longitudinally at 11, 11. The bed or shelf is furnished with side-guides for a shuttle applied to the shuttle-rest. Such side-guides in the present instance are constituted byraised lips 12, 12, at front and rear of'the opening 6 When a shuttle is properly applied to the shuttle-rest, the endgages and side-guides position it so that the vertical opening through the shuttle registers with the opening 6 of the shuttle-rest. The pusher 9 may be of any approved construction adapting it for the purpose herein indicated. It may be variously applied and supported. Herein, it is in the form of an arm that is mounted to swing 9*, such support being provided in connection with a bracket 13 projecting rearward from the casting of which the bed or shelf forms part. The

raised position by means of a spring 14, as

in Figs. 1 and 3, the limit of its rising movement-being determined by means of a stop-projection 9 with which it is furnished, 3, which strikes against the bracket 13. The acting portion of the pusher is constructedand arranged to enable it to act against a fresh weft-carrier on, Fig. 3, located immediately above the weft chamber .of a' shuttle that has been applied to the shuttle-rest, and push it into the said weftchainber, thereby placing it within the grasp of the clip or retainer 3 In Fig. 3 the fresh weft-carrier a is shown resting upon the weft-carrier as already occupying the weft-chamber of the shuttle. As the fresh weft-carrier enters the weft-chamber it expels the weft-carrier x from the shuttle downward through the opening 6. The extent of the working stroke of the pusher 9 is regulated by means of an adjustmentscrew 15 applied thereto which terminates the said stroke, by striking upon the stopprojection 16 in connection with the shelf or bed, when the fresh weft-carrier has been fully introduced into the grasp of the clip or retainer. This stop-device prevents the fresh weft-carrier from being driven too far. For the convenient actuation of the pusher by hand, it is shown furnished with a handle 9*. For the convenient actuation of the pusher by foot, a treadle 17 is provided, in operative connection with the pusher. The said treadle is held normally in a raised position by means of a spring 18, and it is shown as combined operatively with the pusher by means of a rod-connection 19, 20. The lower rod-section 19 is connected pivotally at its lower end to the treadle, and the upper rod-section 20is connected pivotally to the pusher. vThe two rod-sections are connected operatively with each other by forming said upper rod-section with an eye 20, Fig. 1, through which the upper portion of lower rod-section 19 extends. The said upper portion has a head 19 above the said eye. Normally, the spring 18 holds elevated the treadle and the rodsection with its head 19*, so that spring 14 is free to operate to cause pusher 9 to occupy its normal elevated position. When the treadle is pressed down, the downward movement of rod-section 19 causes its head 19 to act upon eye 20 to draw down rodsection 20, thereby actuating the pusher. When the pressure upon the treadle is relieved, the treadle and pusher are raised to their normal positions again by their respective springs. The described construction enables the pusher to be operated manually by either hand or foot, and the loose connection between the pusher and treadle enables the pusher to be operated by hand without incidentally communicating movement to the treadle. By arranging so that the inserted may be operated by foot, both hands of the attendant are left free to be used in handling and placing the shuttle and fresh weft-carrier, and in finding and drawing off the leading end of the yarn therefrom. One hand may be used to hold the weft-carrier in position to be acted upon by the inserter, while the'other holds the end of the yarn extended and may be employed in threading the shuttle in the not being required to move for the performance of the said operation.

In Figs. 4, 5 and 6 the shuttle-rest 6 is mounted by means of downward extensions or legs 6 6 thereof upon a pivotal pin 22, carried by the casting 23 attached to the upper end of the standard or post 7*. It is shown in said figures in its normal position,

in which it may rest against a backstop 24. As applied to the shuttle-rest, the shuttle 3 lies on one lateral side upon the shelf of the shuttle-rest, with its opening directed from front to rear. At the rear of the shelf upon which the shuttle is placed, the shuttle-rest is provided with an upright back 6 having an opening 6' therethrough for the escape of a weft-carrier expelled from the shuttle.

Below the said opening the shuttle-rest is furnished with an inclined plate 6 to deflect rearwardlythe expelled weft-carrier as itfalls from the opening 6. Lateral wingportions of the shuttle-rest are furnished with forwardly-projecting end-gages 8, 8", for engagement with the shuttle-tips, to locate the shuttle endwise. These end-gages are provided with inwardly-projecting portions 8. 8, to engage with the shuttle-tips in front so as to prevent displacement of the shuttle forward. A handle 8 serves for enabling the shuttle-rest to be swung relative to the weft-carrier inserter. The wef carrier inserter 9 is in this instance a fixture upon the casting It is formed with rests B and 9 for the head or base and tip of the fresh weft-carrier ac which is to be introduced into the shuttle, and between such rests it is formed to support the said weftcarrier against forward thrust as the shuttlerest and shuttle are swung toward the weftcarrier inserter. An end-gage 9 upon the inserter alongside the rest for the base or head of the weft-carrier a" insure the proper position of the said weft-carrier lengthwise with respect to the shuttle-chamber, so that the weft-carrier shall properly enter such chamber and its head or base shall become engaged properly with the clip or retainer of the shuttle. I

The employment of shuttles of the class herein referred to, and of a'shuttle reloader such as described greatly facilitates and expedites the work of reloading spent shuttles, so that this part of the work may be performed more readily and quickly than heretofore. This enables the weaver to look after more looms even when he performs the duty of reloading the spent shuttles himself, and when a bobbin-boy is employed to distribute weft or filling to the different looms operative to efiect the reloading of a shuttle which has been removed from a loom in which such shuttle is employed, the said reloader comprising a shuttle-rest for a shuttle free from the said loom,a weft-carrier inserter distinct from the elements of the regular automatic weft-replenishing mechanism of a loom and actingin the direction of the said through-passage, and means for operating the parts at the will of the operative to insert afresh weft-carrier bodily transversely into the clip or other grasping means of the said shuttle and expel the weft-' carrier previously contained in the shuttle.
